Tackle Marcus Gilbert and safety Mike Mitchell had tweaks made to their contracts that won't affect their income for the 2015 season. However, the money they were slated to make from their salaries and roster bonuses are being applied as signing bonuses to free up cap space for the upcoming league year.

The restructured signing bonuses will be prorated and affect their cap number for future seasons.

The restructured deals were likely done to help free up money to re-sign linebacker Jason Worilds, linebacker Arthur Moats and cornerback Brice McCain.

The Steelers have restructured the contract of tackle Marcus Gilbert to create $3.724 million in cap space for the 2015 season. Gilbert, who signed a five-year, $30.815 million contract extension with the Steelers last August, had a roster bonus of $3.5 million and $1.5 million of his base salary converted to a signing bonus. His new base salary for the calendar year is $745,000.

The Steelers have cleared two of their three significant probables for their Sunday game against Atlanta. Tackle Marcus Gilbert (ankle) has been ruled out. The two green-lighted are cornerback William Gay (quad) and center Maurkice Pouncey (ankle).

The Steelers have listed corner back Ike Tayloras doubtful for Sunday's game against the Falcons. Taylor, who left last week's game against the Bengals with a forearm injury, was unable to practice most of the week.

Linebacker James Harrison , who missed last week's game with a knee injury, is questionable.

The following players are probable for Pittsburgh: Ben Roethlisberger, William Gay, Marcus Gilbert, Cameron Heyward, Heath Miller and Maurkice Pouncey.
